One drag, one probe, thirty gravity wells. Read the curve before you commit to it — then thread every star on the way to the beacon.





HOW A SHOT WORKS
There is no timer and no randomness. A shot is decided the moment you release, which means a miss is always something you can correct.
Touch the sky and drag. Direction is the way you pull; distance is the power. The amber ring around the probe fills as you wind it up.
The forecast shows the entire flight before you let go — every bend around every planet, right up to the beacon. You are solving a puzzle, not guessing.
Gravity does the steering. Skim a planet and the probe whips around it; clip one and the flight ends. Arrive in the ring to clear the level.
THIRTY ROUTES
Every level was built by searching the whole space of launch angles and speeds, then keeping only the routes that demand a real curve. Every stored solution is re-simulated by the test suite on each build, so no route can quietly become impossible.
One well, wide lanes, three stars a route. Room to learn how a pull becomes a curve.
Two wells pulling against each other. The lane narrows and the arcs start crossing.
Three worlds at once. Five stars a route, and nowhere to waste a degree.
WHAT IT DOES NOT DO
Slingwell is a paid-up-front game with nothing else bolted on. It has no networking code at all, so there is nothing to phone home with.
Levels and stars are written to the app's own storage. Delete the app and they are gone.
Sound is synthesised on the device and respects the silent switch. Haptics can be switched off in Settings.
Aeroplanes, tunnels, bad hotel Wi-Fi. Nothing in the game needs a connection.
PRIVACY POLICY
Last updated 20 October 2026
Slingwell does not collect personal data. There is no sign-in, no account and no profile. The game stores a small amount of progress data — which levels you have cleared and how many stars you earned on each — inside the app's own storage on your device.
The app contains no networking code, no analytics SDK, no advertising SDK and no crash reporting service. Your progress never leaves the device unless you back the device up yourself through Apple's own backup features.
Slingwell is a paid app with no in-app purchases and no subscriptions. Apple processes the purchase and handles any refund request; Slingwell never sees your payment details.
Slingwell is rated 4+ and is suitable for all ages. Because the app collects no data at all, it complies with the Children's Online Privacy Protection Act (COPPA) and with the EU General Data Protection Regulation (GDPR) by design rather than by policy.
You can erase all stored progress at any time from Settings, and deleting the app removes everything the game has written. Both actions are immediate and irreversible.
If a future version ever changes any of the above, this document will be updated before that version ships, and the change will be described in the release notes.
Questions about this policy can be sent to support@slingwell.app. We answer within two business days.
TERMS OF USE
Last updated 20 October 2026
Slingwell is licensed, not sold. You may install and play it on any Apple device that you own or control, as permitted by the App Store Terms of Service. You may not redistribute, resell, reverse engineer or republish the app or its assets.
Play fair. Do not tamper with the app's files, attempt to bypass its level progression, or use it in any way that breaks the law where you live.
The game, its artwork, its level design and its source code remain the property of the developer. Feedback you send us may be used to improve the game without any obligation to you.
Slingwell is provided "as is". We work hard to keep it free of defects, but we cannot promise that it will run without interruption on every device or every version of iOS. To the extent permitted by law, we exclude all implied warranties.
To the extent permitted by law, the developer is not liable for any indirect or consequential loss arising from the use of the app. Nothing in these terms limits rights you have under mandatory consumer law in your country of residence.
The licence ends if you delete the app or if you breach these terms. Sections 3, 4 and 5 survive termination.
These terms are governed by the laws of the developer's place of residence, without regard to conflict-of-law rules. Disputes may also be raised through Apple's standard App Store complaint process.
